About TerraJ

TerraJ is a set of fractal terrain and solar system generation
programs that have been ported from C/C++ to Java.

The port has included extensive refactoring, the creation of a
documented API to enable reuse of parts of them in other programs and
extensions to the original
programs such as new Swing user interfaces. Full
javadoc for all the classes in the project is available.

Example images from the programs are shown below. Click for
